Replacing 'foo' with 'foobar'? Sounds like someone's got a case of the Mondays.

The question is about sed, but I'm feeling a little frazzled. Maybe I should try something more soothing, like awk.

Seriously, who would choose Option C? Piping the output to the file name is just nonsensical.

I think Option B is the best choice. Redirecting the output to the same file is a surefire way to update the contents.

Option D is the way to go. The '-i' flag modifies the file in place, which is exactly what the question asks for.

Option A is the correct answer. It uses the 's' command to replace 'foo' with 'foobar' and the 'g' flag to replace all occurrences.

I'm not sure, but I think option D makes sense because it uses -i flag for in-place editing.

I agree with Larae, using -i option will change the file in place.
